Eric Decker, Jessie James Decker Exit Special Forces After Brutal Injury

The exhausted father of four could barely walk back to basecamp after he noted he "popped" something.

Despite the agony, Eric, who was having painful back spasms, vowed to continue fighting in the competition.

"I'm gonna push myself 'til exhaustion," he said in a confessional. "My attitude and determination, I feel like, will push me through. I know it's going to be difficult. I'm gonna do it until my body says 'no.'"

Unfortunately, a visit to Special Forces' Dr. Andy Brown confirmed that his body had officially had enough.

As the doctor told Eric, "I'm concerned we can't inflict any more punishment on your hip. I don't think that we can really safely let you carry on."

And with that, Eric was forced to medically withdraw himself on day six, but not before noting, "I don't consider myself a quitter."

When he broke the news to his wife, Jessie didn't hesitate and replied, "I'm going with you."

The singer voluntarily withdrew herself to return home and support her injured husband.

As they held hands and exited camp together, Jessie lovingly declared, "We ride together, we fly together."

But Eric and Jessie weren't the only stars who left the show. Keep reading to see who else exited on day six, plus the eight celebs still fighting to make it to the end of training.
